What is Two-Factor Authentication?
Two-factor authentication (TFA) adds a second layer of security to your online accounts. Verifying your identity using a second factor (like your phone or other mobile device) prevents anyone but you from logging in, even if they know your password.
SFA implemented Duo in Fall 2020.
How It Works
-
Enter your mySFA username and password as usual
-
Use your phone, or other TFA option, to verify your identity
-
Securely logged in
Once you've enrolled in Duo you're ready to go! You'll login as usual with your mySFA username and password, and then use your device to verify that it's you.
No mobile phone? You can also use a landline or tablet. If you would rather use a hardware token contact the IT Security team for additional details. Duo lets you link multiple devices to your account, so you can use your mobile phone and a landline, a landline and a hardware token, two different mobile devices, etc.
Why Do I Need This?
Passwords are increasingly easy to compromise. They can often be stolen, guessed, or hacked — you might not even know someone is accessing your account.
Two-factor authentication adds a second layer of security, keeping your account secure even if your password is compromised. With Duo Push, you'll be alerted right away (on your phone) if someone is trying to log in as you.
This second factor of authentication is separate and independent from your username and password — Your password is never shared with Duo.
